Using BIOS
CAS Latency (Tcl) (4.0)
Memory CLK (200 MHz)
This item is used to set the memory clock mode.
RAS/CAS Delay (Trcd) (3 CLK)
This item specifies the Row precharge to Active or Auto-Refresh of the same bank.
Row Precharge Time (Trp) (3 CLK)
This item controls the timing delay (inclockcycles) before the DRAM starts a read
command after receiving it.
This is the amount of time a CAS is performed after a RAS. The lower the better, but
some DRAM does not support low figures.
Press <Esc> to return to the M.I.B. (MB Intelligent Bios) page.
This item determins the time RAS takes to read from and write to a memory cell
.
Min Active RAS (Tras) (9 CLK)
Row Cycle (Trc) (12 CLK)
Use this item to specify the Row Cycle Time.
RAS/RAS Delay (Trrd) (2 CLK)
This item specifies the active-to-active delay of different banks.
Bank Interleaving (Auto)
This item is used to set the bank interleaving.
Spread Spectrum (Spread All Clocks)
If you enable spread spectrum, it can significantly reduce the EMI (Electro-Magnetic
Interference) generated by the system.
Auto Detect DIMM/PCI Clk (Enabled)
When this item is enabled, BIOS will disable the clock signal of free DIMM/PCI slots.
Voltage Function (Disabled)
Use this item to enable or disable the Voltage Function. If enable, users can increase
the hardware voltage through BIOS settings.
CPU/HT Reference Clock (MHz) (200)
Use this item to set the CPU/HT Reference Clock through clock gen.
Warning: Please pay attention that doing overvoltage may result in damage
to hardware.
DRAM Timing Mode (Auto)
This item enables you to specify the DRAM timing mode to be configured automati-
cally or manually.
SB Clock Spread Spectrum (Disabled)
This item is used to enable or disable the Southbridge clock spread spectrum.
HT Frequency (Auto)
This item enables users to adjust the HT frequency. The default setting is auto and we
recommend users leave the setting unchanged. Modify it at will may cause the system
to be unstable.
